But ironically, that's when singers do best. It's a double edge sword to pick big explosive and complex song, if it doesn't really suit you. However I do wish the other singers are more like him, pick songs that he likes, that maybe is what he wants to express, or something he wants to share because is meaningful to them, but the important thing is, also know that its a song he can pull off. He wasn't the only one, but I get what you mean. His journey in the show reminds me of ZhouShen, they pick songs, that are interesting or meaningful, and still picks songs that go a little outside of their comfort zone, but they know they can pull it off.
